Answer:
1 gallon every 16 minutes
Step-by-step explanation:
If after 32 minutes the container has 6 gallons left that means it has lost 2 gallons of water. So we now divide the 32 minutes by the 2 gallons of water to get that 1 gallon of water leaks every 16 minutes.

The type of sample that can be considered unreliable is type (a), in which responses are voluntary.
Step-by-step explanation:
The type of sample that can be considered unreliable is type (a), in which responses are voluntary.
It can be considered unreliable because being voluntary, the answers will give a biased result and the analysis will not be valid.
The rest of the options, if the necessary collections are taken, are samples that can be considered reliable.
Answer:
D. Runner B; Runner B will catch up to Runner A 3.5 hours after Runner A crosses the starting line.
Step-by-step explanation:
Runner A:
Time it takes for him to finish:
t = 26.2/5.6 = 4.679 hours (to complete race)
.
Runner B:
Time it takes for him to finish:
t = 26.2/6.4 = 4.094 hours
BUT wait, we have to account for the extra .5 hours -- the time it took for him to cross the start line.
t = 4.094 + .5 = 4.594 hours
Answer:
Step-by-step explanation:
2)
80 +67 +97+ 98 +85 +72 = 499
499/6=83.1666666667
Average: 83.1666666667
3)
a) <em>97</em> <u>93</u> 92 90 90 <u>90</u> <em>86</em> =90
median of Edgars grades for his midterm is 90
<em>99</em> <u>93</u> 93 89 88 <u>88</u> <em>86</em>
median of Edgars grades for his trimester is 89
7)
(z+9+18)= z+27 (remember don't mix the numbers if they are attached to the x)
(z+18+9)= z+27 (because adding is both ways the same)
a) a + b =b + a
Geometry
1.
a) 6x^2
b)The surface area of a cube = 6a^2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, x is just the length of one side of a cube
c) The unit would be sq(squared) feet
